Groupon or rather GRPN might be under a lot of pressure now, because their acquisition costs for new deals is (still) very high and they face tremendous competition all over the globe (esp. from more versed local competitors - you really need to know a local market to create good deals). anyway if groupon stays innovative (for example in terms of their deals creation - eg. using an automated process, rather than cold calling OR creating significant social buzz around a lot of their deals) then I believe in the long term they have one of the most sustainable businesses out there (although with rather low margins)
